CONCEALED R INVISIBLE BUTT-HINGE.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed September 23, 1919. Serial No. 325,620.

^ cealed or Invisible Butt-Hinges, whereof the following is a specifica-tion, reference being had to the accompanying drawings.

The invention relates to concealed or invisible hinges, ordinarily known as butthinges, which are especially adaptable for mounting doors of coaches, automobiles, etc., and is an improvement over the type of hinge shown, and described in a patent, Serial Number 1,249,700 granted me under date of September 11, 1917.

In its general aspect, the present invention is similar to that of the patent in that the hinge comprises a pintle supporting member, which is relatively adjustable with respect to a socket member or casing adapted for permanent attachment to the structural frame, or mounting, to which the door is hung. i

The object of the present invention is to afford, in addition to the capacity for relative adjustment of the parts above referred to, a means whereby said parts are held against .displacement after the adjustment is secured, and which in the course of the adjustment, automatically compensate for the relative shifting of said parts.

The structure, whereby, I attain these ends will be better understood from the de-A tailed description which follows:

In the accompanying drawings, Figure I is a view partly in section, and partly in elevation illustrating a portion of a door, and its supporting structure together with my improved hinge as applied thereto.

Fig. II is a face view of the hinge, a certain portion of the movable element being cut away, so as to facilitate the showin@ of the parts behind.

*ig III is a cross sectional yiew through the hinge along the plane indicated by the arrows III-III in Fig. I

The hinge, las herein shown, comprises a socket member or casing 1, recessed within a suitable receiving opening in the structural frame or pillar post to which the door ing is hung. This casing is integrally formed with a face plate 2, having suitable openings for screws 3, 3, by which attachment to the mounting structure is effected.

Concealed within the hollow of the socket casing 1, vis a pintle carrying member 5, which is also formed with an integral facplate 6, received within a recess 7 in the face plate 2, of the casing. 'The member 5, has spaced lugs 88, between which is mounted the inwardly projecting curved arm 9, of the movable member of the hinge, connection being effected by a fulcrum pintle 10.4 The movable hinge member also comprises a face plate 11, and is secured to the door 12, by screws 13, as shown in Fig. I. Adjustment between the casing and the pintle supporting member 5, is effected by means of screws 15, two being preferably employed in the present instance for the purpose designated. These screws are headed as at 16 to engage the face plate of member 5, `and their shank ends are threaded into cooperative receiving holes 17 in the casing member l. Disposed within sockets formed in integral offsets 18, of the casing member, and encircling the screws 15, are comparatively stout helical springs Q0.

By reason of this interposition these springs tend to force the member o, outwardly relative to the tion to the screws 15. ment of the hinge, expand, as the case may be, to compensate for the shifting of the member 5, and, after the desired adjustment is secured, are further functional by virtue of their great tenacity in holding the screws against accidental rotation; and at the same time pre venting rattling of the associated parts. This feature is of utmost importance, when considered in connection with application to automobiles, or other vehicles Where the hinge elements are apt to work loose, due to vibration.
